3024 switches loose HTTP accessibility
We have ~20 3024 switches that will loose the ability to be HTTP managed. We upgraded to the 6.0.4 firmware but that has not helped. Essentially the switches still work in that they do pass traffic. When they are initially turned on they are able to be managed via HTTP. After a period of time (it seems to vary from days to weeks) they suddenly cannot be managed. Any attempt to HTTP connect to the IP only results in the web page timing out.
We are able to ping the IP and the device does respond, and as I said, it does pass traffic. We are able to manage the switch via the console port. My tech even tells me they can still get statistics out via snmp software such as Observer. The problem seems to be that of the HTTP interface.
Does anyone else have this problem? Does anyone else know how to resolve this?
Any help you can provide would be appreciated.

Hey there,
You don't need to assign a different IP on a certain port. The IP Address I was referring to earlier should be assigned to the switch itself and not the port. This way, there's no need for you to dedicate a separate machine just for this purpose. You can keep your machine within the DATA VLAN (192.168.1.x) and still access the switch in the Managerment VLAN (192.168.100.x) directly from your machine...of course with the help of the static routes in your router to route 192.168.100.x network and use the switch address as the gateway. Does this make sense to you?
I've gone through the same thing before where I had connected a machine on one of the ports and used that to configure the switch...but the darn thing stops all the time. It's quite an annoyance and obviously there's something wrong if you have clear out the ARP Cache all the time.
BTW, have you upgraded the firmware?
Give what I told you a shot and hopefully, it'll make your life easier in harmony. I'm not a DELL tech. All of my advices to you just came from experience and I'm hoping to share what I've learned to other people out there. I hope this works for you bud!

Tad,
It's been 5 months since I last touched those Dell switches. Sorry.

Dell has new firmware available for this switch. It was released July 30. We'll try installing it here and see if it addersses our original problem. Thanks for all the suggestions!! I'm happier just knowing I'm not the 'only' person with this problem. (albeit I'd prefer none of us had this problem....)
The firmware is available here:

Good move! We exactly did the same thing and replaced everything with Cisco's multilayered switches. I just didn't bother mentioning it for ethical reasons
. Everything actually turned up better than we expected.

Well...it's been a while and I don't see a Dell Tech offering any help with this one. I guess we live it until the next version of software? We've since yanked the Dell switch and put in a Cisco Catalyst. These Dell switches aren't quite ready for the enterprise yet....maybe a small workgroup.

Can I ask how you delete the ARP cache? From a machine, or from a telnet session on the switch? If this works 100% of the time, I will just do this once a month to clear the units proactively.

We have a CISCO core switch that is being used as a router by our WAN provider. As it turns out CISCO has a protocol called Cisco Discovery Protocol (CDP) that the Dell switches cannot handle. In speaking with Dell tech support they suspected this was the cause. We contacted the WAN provider and had them turn off CDP on the LAN side of their router.
Now that the Cisco switch is not sending out the CDP packets, our Dell 3024 switches no longer lose the HTTP manageability. It least they've been holding steady for a couple of weeks now...
With luck, this has resolved our problem.
